From 16a48f83f6c37a7004c6586951df9522ada96400 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Fri, 11 Feb 2005 10:13:07 +0000 Subject: [PATCH] gas/ 2005-02-11 Jan Beulich * config/tc-ia64.h (LEX_AT): Include LEX_BEGIN_NAME. (LEX_QM): Likewise. (ia64_parse_name): New third parameter. (md_parse_name): Pass third argument. * config/tc-ia64.c (pseudo_func): Placeholders use NULL as name.
